Wow, can't believe my luck at stumbling into the solution for this so quickly..
Code:
osgViewer::Viewer::Windows windows;
viewer.getWindows(windows);
for(osgViewer::Viewer::Windows::iterator itr = windows.begin();
itr != windows.end();
++itr)
{
osg::State *s=(*itr)->getState();
s->resetVertexAttributeAlias(false, 8); // <-- This line
s->setUseModelViewAndProjectionUniforms(true);
s->setUseVertexAttributeAliasing(true);
}
Here is a before / after: http://imgur.com/a/aWoKB
It looks like if you use vertex attribute aliasing it compacts the uniform
slots by default, which screws up all fixed transform stuff (which I guess
expects them to be in their usual spots).
s->resetVertexAttributeAlias(false, 8); prevents it from compacting the uniform
slots, and it all works.
